The Fallout series of video games provide a wonderful alternative history that answers the question of what might have happened had the microchip never been invented. Yes, most things run on tubes, and apparently you can implement an AI that passes a Turing test in tubes (does the Turing test apply if you’re comparing it against NPCs?). Of course, as with all of computer history, the coolest parts of Fallout are the computer terminals, so [LowBudgetTech] decided to build one. All the files are available, and if you have a Pi sitting around this is a good weekend project.
This terminal has a host of features that are well-suited for the modern vault dweller. Of note, the entire case is 3D printed, in multiple pieces. Sure, considering the display is an LCD it’s a tiny bit thick, but you don’t get the Atomic age aesthetic without a big CRT, do you? The keyboard is a standard, off-the-shelf mechanical keyboard for clicky goodness with vintage-style keycaps. There’s a 3.5″ USB floppy drive, because there’s nothing that will survive a nuclear holocaust like magnetic media. The rest of the build is a Raspberry Pi 3B+, which is more than enough compute power to open a door shaped like a gear.
As for what you would do with a retro-inspired Pi terminal, well, it would make a good computer for the workbench, and since the case is already designed for a 3.5″ drive, you could use this to archive some old media. If there’s one thing the apocalypse tells us, it’s that these old terminals will still be kicking after a few hundred years.
Right up front, let us stipulate that we are not making fun of this project. Even its maker admits that it has no practical purpose. But this 3D-printed Commodore-style rotary dial keypad fails to be practical on so many levels that it’s worth celebrating.
And indeed, celebrating deprecated technology appears to be what [Jan Derogee] had in mind with this build. Rotary dials were not long ago the only way to place a call, and the last time we checked, pulse dialing was still supported by some telephone central office switchgear. Which brings us to the first failure: with millions of rotary dial phones available, why build one from scratch? [Jan] chalks it up to respect for the old tech, but in any case, the 3D-printed dial is a pretty good replica of the real thing. Granted, no real dial used a servo motor to return the dial to the resting state, but the 3D-printed springs [Jan] tried all returned the dial instantly, instead of the stately spin back that resulted in 10 pulses per second. And why this has been done up VIC-20 style and used as a keypad for Commodore computers? Beats us. It had to be used for something. That the software for the C-64 generates DTMF tones corresponding to the number dialed only adds to the wonderful weirdness of this. Check out the video below.
We’ll hand it to [Jan], he has a unique way of looking at the world, especially when it comes to clocks. We really enjoyed his persistence of phosphorescence clock, and his screw-driven linear clock turns the standard timekeeping UI on its head.

Bakelite, hammertone gray finish, big chunky toggle switches, jeweled pilot lights – these are a few of [Wesley Treat]’s favorite retro electronics things. And he’ll get no argument from us, as old gear is one of our many weak spots. So when he was tasked by a friend to come up with some chaser lights for an Art Deco-themed bar, [Wesley] jumped at the chance to go overboard with this retro-style control panel.
Granted, the video below pays short shrift to the electronics side of this build in favor of concentrating on the woodworking and metalworking aspects of making the control panel. We’re OK with that, too, as we picked up a ton of design tips along the way. The control panel is all custom, with a chassis bent from sheet aluminum. The sides of the console are laminated walnut and brushed aluminum, which looks very chic. We really like the recessed labels for the switches and indicators on the front panel, although we’d have preferred them to be backlighted. And that bent aluminum badge really lends a Chrysler Building flair that ties the whole project together.
All in all, a really nice job, and another in a long string of retro cool projects from [Wesley]. We recently featured his cloning of vintage knobs for an old Philo tube tester, and we’ll be looking for more great projects from him in the future.

If you grew up in the latter part of the 20th century, you didn’t have the Internet we have today — or maybe not at all. What you did have, though, was Radio Shack within an hour’s drive. They sold consumer electronics, of course, but they also sold parts and kits. In addition to specific kits, they always had some versions of a universal kit where lots of components were mounted on a board and you could easily connect and disconnect them to build different things. [RetoSpector78] found a 200-in-1 kit at a thrift store that was exactly like the one he had as a kid and he shares it with us in the video below.
This was a particularly fancy model since it has a nice looking front panel with a few knobs and displays. The book shows you how to make the 200 different projects ranging from metronomes to rain detectors. The projects really fell into several categories. There were practical circuits like radio receivers, test equipment, and transmitters. Then there were games or circuits even the manual called “silly.” In addition, there were circuits to build simply to understand how they work, like flip flops or counters.

Houston’s historic third ward, aka “The Tre,” is
ripe rife with history, and some of that history is digitally preserved and accessible through an art installation in the form of repurposed payphones. We love payphones for obvious reasons and seeing them alive and kicking warms our hearts. Packing them with local history checks even more boxes. Twenty-four people collaborated to rebuild the three phones which can be seen in the video after the break, including three visual artists, three ambassadors, and eighteen residents who put their efforts into making the phones relevant not only to the ward but specifically to the neighborhood. One phone plays sound clips from musicians who lived or still live in the ward, another phone has spoken word stories, and the third has field recordings from significant locations in The Tre.
Each phone is powered by a solar cell and a USB battery pack connected to a Teensy with an audio adapter board, and a 20 watt amplifier. Buttons 1-9 play back recorded messages exclusive to each phone, star will record a message, and zero will play back the user-recorded message. Apps for smart phones are easy for young folks to figure out but the payphones ensure that these time capsules can be appreciated by people of any age, regardless of how tech savvy they are and that is wise as well as attractive. The coin return lever and coin slot also have associated sound clips unlike regular payphones so the artists get extra credit.
Did we say that we love payphones? Yes, yes we did. The very first post on Hackday was for a redbox and that got the ball rolling.

Arduinos are a handy tool to have around. They’re versatile, cheap, easy to program, and have a ton of software libraries to build on. They’ve only been around for about a decade and a half though, so if you were living in 1989 and wanted to program a microcontroller you’d probably be stuck with an 8-bit microprocessor with no built-in peripherals to help, reading from a physical book about registers and timing, and probably trying to get a broken ribbon cable to behave so it would actually power up. If you want a less frustrating alternate history to live in, though, check out the latest project from [Marek].
He discovered some 6502 chips (Polish language, Google Translate link) that a Chinese manufacturer was selling, but didn’t really trust that they were legitimate. On a lark he ordered some and upon testing them he found out that they were real 6502s. Building an 8-bit computer is something he’d like to do, but in the meantime he decided to do a project using one of these chips as a general-purpose microcontroller similar to a modern Arduino. The project has similar specs as an Arduino too, including 8kB of RAM memory, 8kB of I/O address space, and various EPROM capabilities. [Marek] went on to build a shield board for it as well, for easy access to some switches and LEDs. It’s a great build that anyone interested in microcontrollers should check out.
Keep in mind that an ATtiny45 has 8 bits like the 6502 but only costs around $1 USD, whereas a 6502 would have cost around $200 in today’s dollars. It’s really only in modern times that we can appreciate the 6502 as a cheap 8-bit microcontroller for that reason alone, but we can also appreciate how it ushered in a computer revolution since competing Intel and Motorola chips cost around six times more before it showed up. They became so popular in fact that people still regularly use them to build retrocomputers of all kinds.
The RetroPie project is a software suite for the Raspberry Pi that allows the user to easily play classic video games through emulators. It’s been around for a while now, so it’s relatively trivial to get this set up with a basic controller and video output. That means that the race is on for novel ways of implementing a RetroPie, which [Christian] has taken as a sort of challenge, building the tiniest RetroPie he possibly could.
The constraints he set for himself were to get the project in at under 100 mm. For that he used a Pi Zero loaded with the RetroPie software and paired it with a 1.44″ screen. There’s a tiny LiPo battery hidden in there, as well as a small audio amplifier. Almost everything else is 3D printed including the case, the D-pad, and the buttons. The entire build is available on Thingiverse as well if you’d like to roll out your own.
While this might be the smallest RetroPie we’ve seen, there are still some honorable mentions. There’s one other handheld we’ve seen with more modest dimensions, and another one was crammed into an Altoids tin with a clamshell screen. It’s an exciting time to be alive!
